    OK, but nobody pretended the contrary.  You can still extract N bits 
depending on
    the 2^N results, by doing some Fourier transfrom on all results obtained in
    "parallel universes". This means that the 2^N computations have to occur in 

    But they pretend that the number 2^N is so large that it cannot exist in 
    universe, much less in that little quantum computer and therefore there 
must be
    other worlds which contain these enormous number of bits. What Holevo's 
    shows is the one can regard all those interference terms as mere calculation
    fictions in going from N bit inputs to N bit outputs.

Can such "calculation fictions" support conciousness? That's the real question. If they can, then you can't avoid many-worlds (or at least many minds).

Why is that "the real question"? Saying yes to the doctor implies that a classical computer can support consciousness.
